Sea Bindweed thrives in well-drained soil and prefers moderate watering. Allow the soil to dry out slightly between waterings, especially once established. Avoid waterlogging, which can lead to root rot.

Consistent moisture is beneficial during its active growth period.

Pruning is generally minimal for Sea Bindweed. Remove any dead or spent flowers to encourage further blooming.

Light trimming can be done after flowering to maintain shape or control its spread if it becomes too vigorous in a confined space.

Sea Bindweed can be propagated by seeds sown in spring or by stem cuttings taken in summer. Seeds may require scarification or stratification. Cuttings should be rooted in a well-draining medium.

Division of established clumps is also an effective method.

Repotting is rarely necessary for Sea Bindweed as it is often grown in the ground or in large containers. If grown in a pot and it becomes root-bound, repot in spring to a slightly larger container with fresh, well-draining potting mix.
